dancers often mark choreography with their hands, but this duo has taken it to a whole new level. world-class irish dancers suzanne cleary and peter harding performed in riverdance, but now they have become a world phenomenon with their "hand dancing." the two call themselves "up and over it!" and they have choreographed and performed several routines with just their hands. they have appeared on both america's got talent and britian's got talent. maybe you have seen them in this mcdonald's commercial. i might just be guilty of watching this video a few to many times. doesn't it make you just want to break out and dance?!
